Preventing overload in the brain
Brain researchers in Amsterdam have observed a double control system in the hippocampus. This double control system contributes to the memory and ensures that the brain does not `crash`, as is the case during an epileptic seizure. The neurobiologists from the University of Amsterdam carried out... view more (2002-01-29)

UNC study: shape, not just size, impacts effectiveness of emerging nanomedicine therapies
In the budding field of nanotechnology, scientists already know that size does matter. But now, researchers at the University of North Carolina at Chapel Hill have shown that shape matters even more - a finding that could lead to new and more effective methods for treating cancer and other... view more (2008-08-05)

Dominant cholesterol-metabolism ideas challenged by new research
A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL).   view more (2007-08-16)

Adult stem cell breakthrough
The first tissue-engineered trachea (windpipe), utilising the patient's own stem cells, has been successfully transplanted into a young woman with a failing airway. The bioengineered trachea immediately provided the patient with a normally functioning airway, thereby saving her life.   view more (2008-11-19)

OU Cancer Institute Scientists Identify New Cancer Stem Cell Marker; Developing Drug to Stop Cancer Recurrence
After years of working toward this goal, scientists at the OU Cancer Institute have found a way to isolate cancer stem cells in tumors so they can target the cells and kill them, keeping cancer from returning.    view more (2008-09-12)

Heart derived stem cells develop into heart muscle
Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells.   view more (2008-04-24)

Antibody-altering protein found in developing B cells
In order for the B cells of the immune system to identify and fight disease pathogens, they produce a protein called activation-induced cytidine deaminase (AID).   view more (2007-07-20)

Protein suppresses prostate cancer, enhances effects of vitamin E
Researchers have identified a protein that disrupts an important signaling pathway in prostate cancer cells and suppresses growth of the cancer.   view more (2005-11-01)

Malignant tumor or benign cyst?
The results of a study presented today at the Society of Gynecologic Oncology's 39th Annual Meeting on Women's Cancer offer a promising development on the path toward better management of ovarian cancer.   view more (2008-03-11)

Jefferson Scientists Identify Gene Mutation Potentially Involved in Breast Cancer Initiation
Researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia and at the Albert Einstein College of Medicine in New York have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could... view more (2006-06-01)

UK scientists set their sights on cure for AMD
A groundbreaking surgical therapy capable of stabilising and restoring vision in the vast majority of patients who currently suffer blindness through Age-Related Macular Degeneration (AMD) is to be taken to clinical trial by scientists and clinicians at the UCL Institute of Ophthalmology,... view more (2007-06-06)

Protein identified that turns off HIV-fighting T cells
In HIV-infected patients the body's immune system is unable to fight off the virus. A new study to be published online on November 10th in the Journal of Experimental Medicine shows that T cells in HIV-infected individuals express a protein called TIM-3, which inactivates their virus killing... view more (2008-11-10)

Tapping into spinal cures
Stem cells which give rise to vertebrae, muscle and the spinal cord have been identified for the first time by Dr. Valerie Wilson (University of Edinburgh). "These axial stem cells could be used in the future to help replace damaged tissues after back injuries", says Dr. Wilson who will... view more (2004-03-26)

Moderate alcohol consumption enhances the formation of new nerve cells - may contribute to alcohol dependency
Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by... view more (2005-04-26)

U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells.   view more (2006-02-14)

Weak immune response critical to disease that causes most infant hospitalizations
The most common cause of infant hospitalization in the United States, respiratory syncytial virus, infects virtually all children by age two. Along with the influenza virus, RSV is a major contributor to the approximately two million infant deaths worldwide caused every year by respiratory... view more (2007-04-09)

New stem-cell findings can help the body to cure itself
Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell. The study is published in the latest issue of the prestigious scientific journal, Cell.   view more (2006-06-16)

New role for Natural Killers!
Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.   view more (2008-08-28)

Nanoparticles carry cancer-killing drugs into tumor cells
University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells - increasing the drug's cancer-killing activity and reducing its toxic side effects.   view more (2005-06-15)

How to design a cancer-killing virus
One new way to treat individuals with cancer that is being developed is the use of viruses that infect and kill cancer cells while leaving normal cells unharmed.   view more (2007-10-26)

Hunt for DNA amplified in cancers uncovers important target gene
Researchers at Harvard Medical School (HMS) and Massachusetts General Hospital (MGH) have discovered a new cancer-promoting role for a gene potentially involved in breast, liver, and other kinds of cancers.   view more (2006-08-08)

HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system.   view more (2006-08-14)

New directions in tissue repair and regeneration
PHILOSOPHICAL TRANSACTIONS B MAY ISSUE New directions in tissue repair and regeneration - a discussion meeting issue organised and edited by Jeremy Brockes and Paul Martin This volume will consider new information on regeneration and wound healing as biological mechanisms in a variety of... view more (2004-05-04)

Scientists identify cells responsible for relapse after treatment in common childhood cancer
Approximately 20% of children with ALL will experience a relapse of their disease following treatment. Of these, most will never be cured.   view more (2007-03-29)

Scientists discover stage at which an embryonic cell is fated to become a stem cell
